I have a Windows SBS 2008 server with WSUS 3.0 SP1 installed. The updates had been working and then we had some issues with Symantec that resulted in their tech support re-installing IIS 7.0, thus breaking every website run on the server. Since that time, we've been having issues with WSUS.
I just uninstalled WSUS SP2 and installed WSUS 3.0 SP1 again, set up the computer groups, went through the setup wizard, and double-checked that the GPO's are set to Microsoft's standards for SBS. The firewall is open for ports 8530, the GPO is set to go to http://
<servername>:8530, and the WSUS website shows bindings on port 8530, yet I have no PC's showing up in the listing. On the server itself, I tried a few things I found online, including some registry tweaks and "wuauclt /resetauthorization /detectnow" in the cmd prompt, but still nothing. Each time we log into the server itself, it pops up with a "Windows Cannot Check For Updates" window in the taskbar, and when I check for updates in Windows Update, I get the error code "8024400E", which has given me very little direction so far.
Anyone else had similar issues or know what I should be checking? I'll admit that I have not had access to a client PC yet to run the same registry changes and reset the Windows Update stuff, but getting the server PC to show up would be a great start and I assume I could follow the same steps for most other machines on the domain.
Thanks in advance - this has been a real headache.
